Benefits of technology

[0004]Electronic cigarettes are similar to conventional cigarettes in appearance and taste, but less harmful to human's health, so that electronic cigarettes are widely used for helping people to quit smoke. Atomizing devices are key components of electronic cigarettes. A typical atomizing device includes a tobacco oil reserving space and an atomizing assembly. The atomizing assembly has a porous body extending into the tobacco oil reserving space to get the tobacco oil, and the tobacco oil is also sealed by the porous body. However, this configuration may cause the tobacco oil leak out of the atomizing device.

Problems solved by technology

However, this configuration may cause the tobacco oil leak out of the atomizing device.

first embodiment

[0022]Referring to FIGS. 1 and 2, an atomizing device 100 of an electronic cigarette in accordance with a first embodiment is provided. The atomizing device 100 mainly includes a mouthpiece assembly 1, an atomizing assembly 2, and an atomizing sleeve 3. The mouthpiece assembly 1 and the atomizing assembly 2 are received in the atomizing sleeve 3, and are respectively positioned at two ends of the atomizing sleeve 3. The mouthpiece assembly 1 and the atomizing assembly 2 are connected through an air pipe 4 received in the atomizing sleeve 3. A liquid reserving space 5 defined between the atomizing sleeve 3 and the air pipe 4 is for reserving a tobacco oil.

[0023]The atomizing assembly 2 includes an oil obstructing ring 21, a supporting sleeve 22, a screw sleeve 23, a tubular electrode 24, a porous body 25, and a heating coil 26 wrapping around the porous body 25. The porous body 25 is arranged on the supporting sleeve 22, and the oil obstructing ring 21 is arranged on the porous body ...

second embodiment

[0027]Referring to FIG. 5, an atomizing device 200 of an electronic cigarette in accordance with a second embodiment is provided. The atomizing device 200 is similar to the atomizing device 100 illustrated above, the difference that the atomizing device 200 different from the atomizing device 100 is: both of the through hole 225 and the fitting hole 222 are cylindrical shaped, and a diameter of the through hole 225 is greater than that of the fitting hole 222, so that the fitting hole 222 and the through hole 225 form a stepped hole. An elastic member 7 is fixed on the front end 241 between the through hole 225 and the flange 244. The elastic member 7 can be compressed by a movement of the tubular electrode 24 toward the oil valve 6, and can help the tubular electrode 24 return to an original position due to a resilience of the elastic member 7.

third embodiment

[0028]Referring to FIG. 6, an electronic cigarette in accordance with a third embodiment is provided. The electronic cigarette includes an atomizing device 100 and a battery assembly 300. The battery assembly 300 includes a battery 302, a screw sleeve 301, and an electrode ring 303 fixed in the screw sleeve 301. The screw sleeve 301 is threadedly connected to the screw sleeve 23 and the electrode ring 303 contacts and pushes the tubular electrode 24 to move toward the oil valve 6 to open up the oil valve 6 when the battery assembly 300 is connected to the atomizing device 100, thereby, the air passage is got through and the atomized tobacco oil can be sucked out by user. The tubular electrode 24 can return to an original position due to the resilient projection 224 or the elastic member 7 to close the oil valve 6 when the battery assembly 300 is disconnected from the atomizing device 100, thereby, the tobacco oil in the atomizing device 100 would not leak out.

Abstract

An atomizing device includes an atomizing sleeve; a mouthpiece assembly and an atomizing assembly received in the atomizing sleeve. The atomizing assembly includes an oil obstructing ring, a supporting sleeve, a porous body being fixed between the oil obstructing ring and the supporting sleeve, a heating wire wrapping around the porous body, a screw sleeve located at an end of the atomizing sleeve, an insulated ring and an tubular electrode received between the screw sleeve and the insulated ring. An oil valve is formed between the supporting sleeve and the tubular electrode, or between the tubular electrode and the insulated ring; the oil valve is opened or closed by a movement of the tubular electrode, and the oil valve is configured as an air passage in communication with the air pipe when the oil valve is opened. An electronic cigarette using the atomizing device is also provided.

Description

BACKGROUND[0001]1. Technical Field[0002]The present invention relates to atomizing devices, and particularly to an atomizing device and an electronic cigarette having the atomizing device.[0003]2. Description of Related Art[0004]Electronic cigarettes are similar to conventional cigarettes in appearance and taste, but less harmful to human's health, so that electronic cigarettes are widely used for helping people to quit smoke. Atomizing devices are key components of electronic cigarettes. A typical atomizing device includes a tobacco oil reserving space and an atomizing assembly. The atomizing assembly has a porous body extending into the tobacco oil reserving space to get the tobacco oil, and the tobacco oil is also sealed by the porous body. However, this configuration may cause the tobacco oil leak out of the atomizing device.[0005]What is needed, therefore, is an atomizing device and an electronic cigarette which can overcome the above shortcomings.BRIEF DESCRIPTION OF THE DRAWI...
